This United States Patent Application is a continuation of U.S. patent application Ser. No. 15/410,636, filed Jan. 19, 2017, which claims the benefit of United States Provisional Patent Application No. 62/299,499, filed Feb. 24, 2016, and U.S. Provisional Patent Application No. 62/280,354, filed Jan. 19, 2016, each hereby incorporated by reference herein.

I. SUMMARY OF THE INVENTION

A broad object of a particular embodiment of the invention can be to provide a connector system for releasably connecting together tubes, for example medical tubing, and methods of making and using such a connector system, whereby the connector system includes a female coupler having a first passageway, a male coupler having a second passageway, a catch movably coupled to the female coupler, and a catch-receiving element coupled to the male coupler. Upon releasable matable axial coupling of the female and male couplers, the catch engages with the catch-receiving element to fix an axial position of the female coupler in relation to the male coupler, thereby achieving a connected condition of the connector system in which the first and second passageways dispose in fluidic communication to provide a fluid flow path. The connector system further includes a release element movably coupled to the female coupler, whereby travel of the release element along or over a female coupler outer surface of the female coupler disengages the catch from the catch-receiving element to achieve a disconnected condition of the connector system.

Another broad object of a particular embodiment of the invention can be to provide the connector system as described above, further including at least one valve operable to interrupt fluid flow through a passageway, whereby the valve is biased by a valve-biasing member disposed external to or outside of the passageway and accordingly, external to or outside of the fluid flow path when the female and male couplers releasably matably couple to achieve the connected condition of the connector system.

Naturally, further objects of the invention are disclosed throughout other areas of the specification, drawings, and claims.

III. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Now referring primarily to FIG. 1A, which illustrates a method of using a particular embodiment of a connector system (1) for releasably connecting together tubes (2), such as medical tubing employed in a bio-medical environment. Advantageously, the connector system (1) can be relatively easily and securely connected, and yet relatively easily intentionally disconnected.

Now referring primarily to FIG. 1B through FIG. 7F, the connector system (1) includes a female coupler (3) having a first passageway (4) and a male coupler (5) having a second passageway (6). Upon releasable matable axial (or longitudinal) coupling of the female and male couplers (3)(5) (or, stated more concisely, upon connection of the female and male couplers (3)(5)), a connected condition (7) of the connector system (1) is achieved, disposing the first and second passageways (4)(6) in fluidic communication to provide a fluid flow path (8).

For the purposes of the present invention, a longitudinal direction can considered parallel to the first passageway (4), the second passageway (6), and/or the fluid flow path (8).

As to particular embodiments, the connector system (1) can further include a catch (9) movably coupled to the female coupler (3) and a catch-receiving element (10) coupled to the male coupler (5). Upon connection of the female and male couplers (3)(5), the catch (9) engages with the catch-receiving element (10) to fix an axial position of the female coupler (3) in relation to the male coupler (5), thereby achieving the connected condition (7) of the connector system (1).

As to particular embodiments, the connector system (1) can further include a release element (11) movably coupled to the female coupler (3), whereby travel of the release element (11) along or over a female coupler outer surface (12) of the female coupler (3) disengages the catch (9) from the catch-receiving element (10) to achieve a disconnected condition (13) of the connector system (1).

For the purposes of the present invention, the term “catch” means a restraint which, upon matable engagement with a catch-receiving element (10), can function to partially or completely restrain travel of an associated component, such as a female coupler (3).

For the purposes of the present invention, the term “catch-receiving element” means a restraint which, upon matable engagement with a catch (9), can function to partially or completely restrain travel of an associated component, such as a male coupler (5).

As to particular embodiments, the connector system (1) can be configured to provide a connection indicium upon successful releasable matable axial coupling of the female and male couplers (3)(5) to achieve the connected condition (7), whereby the connection indicium can be a visible indicium, an audible indicium, a tactile indicium, or the like, or combinations thereof.

Release Element

Now referring primarily to FIG. 2G, FIG. 2H, and FIG. 3G through FIG. 3I, as to particular embodiments, the release element (11) can be configured as a cam and the catch (9) can function as a follower, whereby the release element (11) can transform input motion into reciprocating motion of the catch (9).

For the purposes of the present invention, the term “cam” means a movable element in a mechanical linkage, whereby the cam can have an irregular periphery and may be useful in transforming motion, for example transforming motion in a first direction into motion in a second direction.

For the purposes of the present invention, the term “follower” means a movable element in a mechanical linkage, whereby movement of the follower results from movement of the cam.

For example, linear or sliding motion of the release element (11) along the female coupler outer surface (12) can be transformed into inward or outward motion of the catch (9) such that the catch (9) can move either inwardly toward the interior of the female coupler (3) or outwardly away from the interior of the female coupler (3).

The release element (11) can be biased by a release element-biasing member (14) which biases the release element (11) toward a release element first position (15), as shown in the examples of FIG. 2G and FIG. 3G through FIG. 3I.

As to particular embodiments, when in the release element first position (15), the release element (11) can bias the catch (9) inwardly toward the interior of the female coupler (3) to engage the catch (9) with the catch-receiving element (10) and achieve the connected condition (7) of the connector system (1).

As but one illustrative example, the release element-biasing member (14) can be configured as a resiliently compressible member (16), such as a spring (for example, a coil spring), whereby when the resiliently compressible member (16) disposes in a non-compressed condition (17), which is the normal biased condition, the release element (11) disposes in the release element first position (15). However, the release element-biasing member (14) need not be limited to this particular configuration.

Now referring primarily to FIG. 2H, upon forcible urging, the resiliently compressible member (16) can be compressed toward a compressed condition (18), disposing the release element (11) in a release element second position (19), allowing the catch (9) to outwardly move away from the interior of the female coupler (3) and disengage with the catch-receiving element (10) to achieve the disconnected condition (13) of the connector system (1).

Travel of the release element (11) along or over the female coupler outer surface (12) can be achieved by the application of forces directed along or over the female coupler outer surface (12), such as forces directed at an angle of between 0° to about ±45° in relation to the female coupler outer surface (12). This is in stark contrast to conventional “quick release” couplers which typically have a release element configured to travel upon the application of forces directed along an axis generally normal (or generally perpendicular) to the coupler outer surface, whereby one illustrative example of this type of release element is a pushbutton release element or a depressible release element. The instant release element (11) is advantageous over the conventional art, as only forces directed at an angle of between 0° to about ±45° in relation to the female coupler outer surface (12) can disengage the catch (9) from within the catch-receiving element (10) to achieve the disconnected condition (13) of the connector system (1), thus precluding inadvertent disconnecting by forces unintentionally applied at an angle of between about ±45° to about 90° in relation to the female coupler outer surface (12).

Now referring primarily to FIG. 2A through FIG. 3I and FIG. 8A through FIG. 8D, as to particular embodiments, travel of the release element (11), which can forcibly urge the resiliently compressible member (16) toward the compressed condition (18), can be longitudinal travel along the female coupler outer surface (12). As but one illustrative example, the longitudinal travel can be between female coupler first and second ends (20)(21).

As to particular embodiments, the longitudinal travel can be sliding travel along the female coupler outer surface (12). Further, as to particular embodiments, the longitudinal travel can be linear or generally parallel to the female coupler outer surface (12), having an angle of about 0° in relation to the female coupler outer surface (12).

Now referring primarily to FIG. 9A through FIG. 12D, as to other particular embodiments, travel of the release element (11), which can forcibly urge a resiliently compressible member (16) toward a compressed condition (18), can be circumferential travel about the female coupler outer surface (12).

As to particular embodiments, the circumferential travel can be rotating travel about the female coupler outer surface (12), whereby the circumferential travel can be any amount of travel about the circumference of the female coupler outer surface (12), whether partially or completely about the circumference of the female coupler outer surface (12). Further, as to particular embodiments, the circumferential travel can be generally parallel to the female coupler outer surface (12).

Now referring primarily to FIG. 12A through FIG. 12D, as to particular embodiments, the circumferential travel can be helical travel about the female coupler outer surface (12).

Embodiment of Catch and Catch-Receiving Element

Now referring primarily to FIG. 2G, FIG. 2H, FIG. 3G, FIG. 3H, and FIG. 4G, as to particular embodiments, the catch (9) can be configured a spherical element, such as a ball (22), and the catch-receiving element (10) can be configured as a retention groove (23) configured to receive a portion or an entirety of the ball (22). However, the catch (9) and catch-receiving element (10) need not be limited to these particular configurations and can be configured as any matable catch (9) and catch-receiving element (10) as would be known to one of ordinary skill in the art.

The ball (22) can be movably coupled to the female coupler (3) proximate the female coupler outer surface (12). For example, the ball (22) can be movably disposed within an opening (24) defined by the female coupler outer surface (12) (as shown in the example of FIG. 1B), whereby the opening (24) can be sufficiently configured to allow movement of the ball (22) through the opening (24) and inwardly toward the interior of the female coupler (3) or outwardly away from the interior of the female coupler (3). Further, the ball (22) can be movably coupled to the female coupler (3) beneath the release element (11).

The retention groove (23) can be coupled to the male coupler (5) proximate a male coupler matable end (25) which is matably received within a female coupler matable end (26) upon releasable matable axial coupling of the female and male couplers (3)(5) to provide the connected condition (7) of the connector system (1). For example, the retention groove (23) can be disposed within a male coupler outer surface (27) proximate the male coupler matable end (25).

Just as engagement of the catch (9) with the catch-receiving element (10) can fix an axial position of the female coupler (3) in relation to the male coupler (5), receipt of the ball (22) within the retention groove (23) correspondingly fixes an axial position of the female coupler (3) in relation to the male coupler (5) to achieve the connected condition (7) of the connector system (1).

Inward movement of the ball (22) can facilitate engagement of the ball (22) within the retention groove (23) upon matable reception of the male coupler matable end (25) within the female coupler matable end (26).

Conversely, outward movement of the ball (22) can facilitate disengagement of the ball (22) from within the retention groove (23), thereby allowing the female and male couplers (3)(5) to disconnect by axial movement away from one another.

Movement of the ball (22) inward and outward and correspondingly, into and out of the retention groove (23), can be controlled, at least in part, by the release element (11), whereby the release element (11) can function as a cam and the ball (22) can function as a follower (as generally described above). Accordingly, linear or sliding motion of the release element (11) along the female coupler outer surface (12) can be transformed into inward or outward movement of the ball (9), causing the ball (9) to move either inwardly toward the retention groove (23) or outwardly away from the retention groove (23).

Now referring primarily to FIG. 2G, FIG. 2H, and FIG. 3G, a release element inner surface (28), which disposes proximate (or adjacent) the female coupler outer surface (12), can provide a cam surface (29) having a ball locking surface (30) and a ball unlocking surface (31).

The ball locking surface (30) downwardly extends toward the female coupler outer surface (12) a greater distance than the ball unlocking surface (31), thereby disposing the ball locking surface (30) closer to the female coupler outer surface (12) than the ball unlocking surface (31). Said another way, the ball unlocking surface (31) upwardly extends away from the female coupler outer surface (12) a greater distance than the ball locking surface (30), thereby disposing the ball unlocking surface (31) farther from the female coupler outer surface (12) than the ball locking surface (30).

Correspondingly, movement of the cam surface (29) over the ball (22) to align (or contact) the ball locking surface (30) with the ball (22) biases the ball (22) inwardly and toward engagement within the retention groove (23) to achieve the connected condition (7) of the connector system (1). Conversely, movement of the cam surface (29) over the ball (22) to align (or contact) the ball unlocking surface (31) with the ball (22) permits the ball (22) to outwardly move away from the retention groove (23), thereby allowing the ball (22) to disengage from within the retention groove (23).

Now referring primarily to FIG. 2G and FIG. 3G through FIG. 3I, the release element-biasing member (14), for example a resiliently compressible member (16), can bias the release element (11) toward a release element first position (15) when in a non-compressed condition (17). When in the release element first position (15), the ball locking surface (30) aligns with (or contacts) the ball (22) and correspondingly biases the ball (22) inwardly and toward engagement within the retention groove (23) to achieve the connected condition (7) of the connector system (1).

Now referring primarily to FIG. 2H, upon forcible urging, the resiliently compressible member (16) can be compressed toward a compressed condition (18), disposing the release element (11) in a release element second position (19) in which the ball unlocking surface (31) aligns with (or contacts) the ball (22), allowing the ball (22) to outwardly move away from the retention groove (23) to achieve the disconnected condition (13) of the connector system (1).

First Valve

As to particular embodiments, the connector system (1) can further include at least one conduit and at least one valve operable to interrupt fluid flow through the conduit.

Now referring primarily to FIG. 2G, FIG. 2H, FIG. 3G, FIG. 3I, FIG. 5G, FIG. 5H, and FIG. 6G, the female coupler (3) can include a first conduit (32) defining a first passageway (4) (which as to particular embodiments, may include a fixed or removable filter) and a first valve (33) operable to interrupt fluid flow through the first passageway (4). The first valve (33) can be movable within a first valve seat (34) to sealably occlude a first port (35) in fluid communication with the first passageway (4), thereby providing a first passageway closed condition (36) in which fluid flow through the first port (35) and accordingly, through the first passageway (4), is interrupted.

The first valve (33) can be biased by a first valve-biasing member (37) which biases the first valve (33) toward a first valve closed position (38) in which the first valve (33) sealably occludes the first port (35), for example by sealably overlaying the first port (35), to provide the first passageway closed condition (36).

Now referring primarily to FIG. 2G, FIG. 2H, FIG. 3G, and FIG. 3I, as but one illustrative example, the first valve-biasing member (37) can be configured as a resiliently compressible member (16), such as a spring; however, the first valve-biasing member (37) need not be limited to this particular configuration.

When in a non-compressed condition (17), which is the normal biased condition, the resiliently compressible member (16) can bias the first valve (33) toward the first valve closed position (38) in which the first valve (33) sealably occludes the first port (35) to provide the first passageway closed condition (36) (as shown in the examples of FIG. 2H, FIG. 3G, and FIG. 3I).

Upon forcible urging, the resiliently compressible member (16) can be compressed toward a compressed condition (18), allowing the first valve (33) to travel within the first valve seat (34) away from the first port (35) toward a first valve open position (39), thus providing a first passageway open condition (40) permitting fluid flow through the first port (35) and accordingly, through the first passageway (4) (as shown in the example of FIG. 2G).

Now referring primarily to FIG. 2G, the resiliently compressible member (16) can be compressed toward the compressed condition (18) upon forcible urging resulting from connection of the female and male couplers (3)(5), thus allowing the first valve (33) to travel within the first valve seat (34) away from the first port (35) toward the first valve open position (39), thus providing the first passageway open condition (40) which permits fluid flow through the first port (35) and accordingly, through the first passageway (4). Further, upon achievement of the connected condition (7) of the connector system (1), the first passageway (4) can fluidicly communicate with the second passageway (6) of the male coupler (5) to provide the fluid flow path (8) through which fluid can flow between connector system first and second ends (41)(42).

In contrast to conventional “quick release” couplers, the instant first valve-biasing member (37) is disposed external to or outside of the first passageway (4) and accordingly, external to or outside of the fluid flow path (8) when the female and male couplers (3)(5) connect to achieve the connected condition (7) of the connector system (1). Correspondingly, fluid flowing within the fluid flow path (8) does not contact the resiliently compressible member (16), which may be advantageous for a plurality of reasons, including elimination of a potential substrate for biofilm growth within the fluid flow path (8) and elimination of a physical impediment to fluid flow within the fluid flow path (8).

Now referring primarily to FIG. 2G, FIG. 2H, FIG. 3G, and FIG. 3I, as a first illustrative example, the first valve (33) can be configured to telescopingly engage with the first conduit (32) such that the first valve (33) telescopingly disposes about the first conduit (32) and can longitudinally travel over the first conduit (32) or longitudinally slide over the first conduit (32).

With this configuration, a first valve inner surface (43) of the first valve (33) can dispose adjacent a first conduit outer surface (44) of the first conduit (32), whereby a fluid-tight seal can exist between the first valve inner surface (43) and the first conduit outer surface (44). As to particular embodiments, an o-ring (45) can be coupled to the first conduit outer surface (44), for example the o-ring (45) can be at least partially recessed within the first conduit outer surface (44), whereby when overlaid by the first valve inner surface (43), the o-ring (45) can function to provide the fluid-tight seal between the first valve inner surface (43) and the first conduit outer surface (44).

The first valve (33) can either partially or entirely surround a portion of the first conduit (32) proximate (or adjacent) the first port (35), depending upon the configuration of the first conduit (32) and the first port (35). As shown in the particular embodiment illustrated in FIG. 2G, FIG. 2H, FIG. 3G, and FIG. 3I, the first valve (33) can entirely surround a portion of the first conduit (32) proximate the first port (35) such that the first valve (33) and that portion of the first conduit (32) are coaxial. Thus, the first valve (33) and the portion of the first conduit (32) proximate the first port (35) can be disposed in concentric relation.

With this configuration, the first conduit (32) and the first valve (33) can together provide a portion of the first passageway (4). More specifically, a first conduit inner surface (46) and the first valve inner surface (43) can define a portion of the first passageway (4). As to particular embodiments, the first conduit inner surface (46) and the first valve inner surface (43) can define a first passageway (4) which is cylindrical or generally cylindrical, having a circular or generally circular cross section (as shown in the example of FIG. 3F).

Again referring primarily to FIG. 2G, FIG. 2H, FIG. 3G, and FIG. 3I, as to particular embodiments, a portion of the first conduit outer surface (44) can provide a first valve seat (34) in which the first valve (33) can move and specifically, in which the first valve (33) can longitudinally travel over the first conduit (32).

The first valve (33) can travel within the first valve seat (34) in a first direction (47) to a first valve closed position (38) in which the first valve (33) sealably occlude the first port (35) in fluid communication with the first passageway (4) (as shown in the examples of FIG. 2H, FIG. 3G, and FIG. 3I), thereby providing the first passageway closed condition (36) in which fluid flow through the first port (35) and accordingly, through the first passageway (4), is interrupted.

When in the first valve closed position (38), the first valve (33) can sealably engage with a first seal assembly (48) which is fixedly coupled to the first conduit (32) in axially spaced apart relation. For example, one or more spacers (49) can fixedly couple the first seal assembly (48) to the first conduit (32) to dispose the first seal assembly (48) in spaced apart relation to the first conduit (32) or to dispose the first seal assembly (48) a distance from the first conduit (32). To provide the first passageway closed condition (36), the first valve (33) can travel within the first valve seat (34) across the distance to sealably engage with the first seal assembly (48) and sealably occlude the first port (35) to interrupt fluid flow through the first passageway (4).

As to particular embodiments, the first conduit (32) and the first seal assembly (48) can be formed as a one-piece construct; however, the invention need not be so limited. As to particular embodiments, the first conduit (32), one or more spacers (49), and the first seal assembly (48) can be formed as a one-piece construct; however, the invention need not be so limited.

As to particular embodiments, the first seal assembly (48) can include an o-ring (45) coupled to an o-ring support (50), for example the o-ring (45) can be at least partially recessed within the o-ring support (50), whereby when overlaid by the first valve inner surface (43), the o-ring (45) can function to provide a fluid-tight seal between the first valve inner surface (43) and the first seal assembly (48).

Now referring primarily to FIG. 2G, FIG. 2H, FIG. 3G, and FIG. 3I, the first valve (33) can be biased by a first valve-biasing member (37) which biases the first valve (33) toward the first seal assembly (48) and correspondingly, toward the first valve closed position (38) to provide the first passageway closed condition (36).

As to particular embodiments, the first valve-biasing member (37) can be configured as a resiliently compressible member (16), such as a spring and for example, a coil spring or a helical spring (51). As to particular embodiments, the helical spring (51) can be disposed about a portion of the first valve (33) to entirely surround that portion of the first valve (33) such that the helical spring (51) and the first valve (33) are coaxial. Thus, the helical spring (51) and the first valve (33) can be disposed in concentric relation.

To reiterate, in contrast to conventional “quick release” couplers, the instant helical spring (51) is disposed external to or outside of the first passageway (4) and accordingly, external to or outside of the fluid flow path (8) when the female and male couplers (3)(5) connect to achieve the connected condition (7) of the connector system (1). Correspondingly, fluid flowing within the fluid flow path (8) does not contact the helical spring (51), which may be advantageous for a plurality of reasons, including elimination of a potential substrate for biofilm growth within the fluid flow path (8) and elimination of a physical impediment to fluid flow within the fluid flow path (8).

Again referring primarily to FIG. 2G, FIG. 2H, FIG. 3G, and FIG. 3I, the helical spring (51) can be disposed between a pair of projecting ribs (52)(53). For example, a helical spring first end (54) can bear against a first rib (52) outwardly extending from the first conduit outer surface (44) and an opposing helical spring second end (55) can bear against a second rib (53) outwardly extending from a first valve outer surface (56).

When in a non-compressed condition (17), which is the normal biased condition, the helical spring (51) can bias the first valve (33) toward sealable engagement with the first seal assembly (48) and correspondingly toward the first valve closed position (38) in which the first valve (33) sealably occludes the first port (35) to provide the first passageway closed condition (36).

Upon forcible urging in a second direction (57) which opposes the first direction (47), the helical spring (51) can be compressed toward a compressed condition (18), allowing the first valve (33) to travel within the first valve seat (34) away from the first seal assembly (48) and away from the first port (35) toward a first valve open position (39), thus providing a first passageway open condition (40) permitting fluid flow through the first port (35) and accordingly, through the first passageway (4) (as shown in the example of FIG. 2G).

Now referring primarily to FIG. 2G, the helical spring (51) can be compressed toward the compressed condition (18) upon forcible urging resulting from connection of the female and male couplers (3)(5), thus allowing the first valve (33) to travel within the first valve seat (34) away from the first seal assembly (48) and away from the first port (35) toward the first valve open position (39), thus providing a first passageway open condition (40) permitting fluid flow through the first port (35) and accordingly, through the first passageway (4). Further, upon achievement of the connected condition (7) of the connector system (1), the first passageway (4) can fluidicly communicate with the second passageway (6) of the male coupler (5) to provide the fluid flow path (8) through which fluid can flow between the connector system first and second ends (41)(42).

Now referring primarily to FIG. 5G, FIG. 5H, FIG. 6G, and FIG. 13A through FIG. 14G, as another illustrative example, the first valve-biasing member (37) can be configured as a resiliently flexible member (58); however, the first valve-biasing member (37) need not be limited to this particular configuration.

When in a non-flexed condition (59) (as shown in the examples of FIG. 13A through FIG. 13G), the resiliently flexible member (58) can bias the first valve (33) toward the first valve closed position (38) in which the first valve (33) sealably occludes the first port (35) (as shown in the examples of FIG. 5H and FIG. 6G).

Upon forcible urging, the resiliently flexible member (58) can be flexed toward a flexed condition (60) (as shown in the examples of FIG. 14A through FIG. 14G), allowing the first valve (33) to travel within the first valve seat (34) toward a first valve open position (39) away from the first port (35), thereby permitting fluid flow through the first port (35) and accordingly, through the first passageway (4) to provide a first passageway open condition (40) (as shown in the example of FIG. 5G).

Now referring primarily to FIG. 5G, the resiliently flexible member (58) can be flexed toward the flexed condition (60) upon forcible urging resulting from connection of the female and male couplers (3)(5), thus allowing the first valve (33) to travel within the first valve seat (34) toward the first valve open position (39) away from the first port (35), thereby permitting fluid flow through the first port (35) and accordingly, through the first passageway (4) to provide the first passageway open condition (40). Further, upon achievement of the connected condition (7) of the connector system (1), the first passageway (4) can fluidicly communicate with the second passageway (6) of the male coupler (5) to provide the fluid flow path (8) through which fluid can flow between the connector system first and second ends (41)(42).

Now referring primarily to FIG. 13A through FIG. 14G, as to particular embodiments, the resiliently flexible member (58) can be configured as a plurality of resiliently flexible members (58) which dispose in circumferentially spaced-apart relation to define an internal space (61). Additionally, an angled surface (62) can be disposed in axially-adjacent relation to the plurality of resiliently flexible members (58).

Upon forcible urging resulting from connection of the female and male couplers (3)(5), the plurality of resiliently flexible members (58) move axially toward the angled surface (62), whereby the angled surface (62) can be received within the internal space (61) while forcibly urging the plurality of resiliently flexible members (58) to flex about the angled surface (62) toward the flexed condition (60) (as shown in the examples of FIG. 14A through FIG. 14G). Correspondingly, the first valve (33) travels within the first valve seat (34) toward the first valve open position (39) away from the first port (35), thereby permitting fluid flow through the first port (35) and accordingly, through the first passageway (4) to provide the first passageway open condition (40).

Upon uncoupling of the female and male couplers (3)(5), the plurality of resiliently flexible members (58) are biased toward the non-flexed condition (59) (as shown in the examples of FIG. 13A through FIG. 13G), biasing the first valve (33) toward the first valve closed position (38) in which the first valve (33) sealably occludes the first port (35).

Again referring primarily to FIG. 13A through FIG. 14G, as to particular embodiments, the resiliently flexible member (58) and the first valve (33) can be formed as a one-piece construct; however, the invention need not be so limited.

Second Valve

Now referring primarily to FIG. 2G, FIG. 2H, FIG. 4G, FIG. 5G, FIG. 5H, and FIG. 7G, the male coupler (5) can include a second conduit (63) defining a second passageway (6) (which as to particular embodiments, may include a fixed or removable filter) and a second valve (64) operable to interrupt fluid flow through the second passageway (6).

The second valve (64) can be movable within a second valve seat (65) to sealably occlude a second port (66) in fluid communication with the second passageway (6), thereby providing a second passageway closed condition (67) in which fluid flow through the second port (66) and accordingly, through the second passageway (6), is interrupted.

The second valve (64) can be biased by a second valve-biasing member (68) which biases the second valve (64) toward a second valve closed position (69) in which the second valve (64) sealably occludes the second port (66), for example by sealably overlaying the second port (66), to provide the second passageway closed condition (67).

Now referring primarily to FIG. 2G, FIG. 2H, and FIG. 4G, as but one illustrative example, the second valve-biasing member (68) can be configured as a resiliently compressible member (16), such as a spring; however, the second valve-biasing member (68) need not be limited to this particular configuration.

When in a non-compressed condition (17), which is the normal biased condition, the resiliently compressible member (16) can bias the second valve (64) toward the second valve closed position (69) in which the second valve (64) sealably occludes the second port (66) to provide the second passageway closed condition (67) (as shown in the examples of FIG. 2H and FIG. 4G).

Upon forcible urging, the resiliently compressible member (16) can be compressed toward a compressed condition (18), allowing the second valve (64) to travel within the second valve seat (65) away from the second port (66) toward a second valve open position (70), thus providing a second passageway open condition (71) permitting fluid flow through the second port (66) and accordingly, through the second passageway (6) (as shown in the example of FIG. 2G).

Now referring primarily to FIG. 2G, the resiliently compressible member (16) can be compressed toward the compressed condition (18) upon forcible urging resulting from connection of the female and male couplers (3)(5), thus allowing the second valve (64) to travel within the second valve seat (65) away from the second port (66) toward the second valve open position (70), thus providing a second passageway open condition (71) which permits fluid flow through the second port (66) and accordingly, through the second passageway (6). Further, upon achievement of the connected condition (7) of the connector system (1), the first passageway (4) of the female coupler (3) can fluidicly communicate with the second passageway (6) to provide the fluid flow path (8) through which fluid can flow between the connector system first and second ends (41)(42).

In contrast to conventional “quick release” couplers, the instant second valve-biasing member (68) is disposed external to or outside of the second passageway (6) and accordingly, external to or outside of the fluid flow path (8) when the female and male couplers (3)(5) connect to achieve the connected condition (7) of the connector system (1). Correspondingly, fluid flowing within the fluid flow path (8) does not contact the resiliently compressible member (16), which may be advantageous for a plurality of reasons, including elimination of a potential substrate for biofilm growth within the fluid flow path (8) and elimination of a physical impediment to fluid flow within the fluid flow path (8).

Now referring primarily to FIG. 2G, FIG. 2H, and FIG. 4G, as a first illustrative example, the second valve (64) can be provided by the second conduit (63) which can longitudinally travel or longitudinally slide within the second valve seat (65).

The second valve seat (65) can be configured to telescopingly engage with the second conduit (63) such that the second valve seat (65) telescopingly disposes about the second conduit (63) to allow longitudinal travel of the second conduit (63) within the second valve seat (65).

With this configuration, a second valve seat inner surface (72) of the second valve seat (65) can dispose adjacent a second conduit outer surface (73) of the second conduit (63), whereby a fluid-tight seal can exist between the second valve seat inner surface (72) and the second conduit outer surface (73). As to particular embodiments, an o-ring (45) can be coupled to the second conduit outer surface (73), for example the o-ring (45) can be at least partially recessed within the second conduit outer surface (73), whereby when overlaid by the second valve seat inner surface (72), the o-ring (45) can function to provide a fluid-tight seal between the second valve seat inner surface (72) and the second conduit outer surface (73).

The second valve seat (65) can either partially or entirely surround a portion of the second conduit (63) proximate (or adjacent) the second port (66), depending upon the configuration of the second conduit (63) and the second port (66). As shown in the particular embodiment illustrated in FIG. 2G, FIG. 2H, and FIG. 4G, the second valve seat (65) can entirely surround a portion of the second conduit (63) proximate the second port (66) such that the second valve seat (65) and that portion of the second conduit (63) are coaxial. Thus, the second valve seat (65) and the portion of the second conduit (63) proximate the second port (66) can be disposed in concentric relation.

With this configuration, the second conduit (63) and the second valve seat (65) can together provide a portion of the second passageway (6). More specifically, a second conduit inner surface (74) and the second valve seat inner surface (72) can define a portion of the second passageway (6). As to particular embodiments, the second conduit inner surface (74) and the second valve seat inner surface (72) can define a second passageway (6) which is cylindrical or generally cylindrical, having a circular or generally circular cross section (as shown in the example of FIG. 4E).

The second valve (64) can travel within the second valve seat (65) in a first direction (47) to a second valve closed position (69) in which the second conduit (63) sealably occludes the second port (66) in fluid communication with the second passageway (6), thereby providing a second passageway closed condition (67) in which fluid flow through the second port (66) and accordingly, through the second passageway (6), is interrupted.

When in the second valve closed position (69), a second seal assembly (75) which is fixedly coupled to the second conduit (63) in axially spaced apart relation via one or more spacers (49) can sealably engage with an engagement surface (76) provided by an inwardly tapering portion of the second valve seat inner surface (72), thus providing the second passageway closed condition (67) in which the second port (66) is sealably occluded to interrupt fluid flow through the second passageway (6).

As to particular embodiments, the second conduit (63) and the second seal assembly (75) can be formed as a one-piece construct; however, the invention need not be so limited. As to particular embodiments, the second conduit (63), one or more spacers (49), and the second seal assembly (75) can be formed as a one-piece construct; however, the invention need not be so limited.

As to particular embodiments, the second seal assembly (75) can include an o-ring (45) coupled to an o-ring support (50), for example the o-ring (45) can be at least partially recessed within the o-ring support (50), whereby when overlaid by the engagement surface (76), the o-ring can function to provide the fluid-tight seal between the engagement surface (76) and the second seal assembly (75).

Again referring primarily to FIG. 2G, FIG. 2H, and FIG. 4G, the second conduit (63) can be biased by a second valve-biasing member (68) which biases the second conduit (63) and correspondingly the second seal assembly (75) toward the engagement surface (76) and correspondingly, toward the second valve closed position (69) to provide the second passageway closed condition (67).

As to particular embodiments, the second valve-biasing member (68) can be configured as a resiliently compressible member (16), such as a spring and for example, a coil spring or a helical spring (51). As to particular embodiments, the helical spring (51) can be disposed about a portion of the second conduit (63) to entirely surround that portion of the second conduit (63) such that the helical spring (51) and the second conduit (63) are coaxial. Thus, the helical spring (51) and the second conduit (63) can be disposed in concentric relation.

To reiterate, in contrast to conventional “quick release” couplers, the instant helical spring (51) is disposed external to or outside of the second passageway (6) and accordingly, external to or outside of the fluid flow path (8) when the female and male couplers (3)(5) connect to achieve the connected condition (7) of the connector system (1). Correspondingly, fluid flowing within the fluid flow path (8) does not contact the helical spring (51), which may be advantageous for a plurality of reasons, including elimination of a potential substrate for biofilm growth within the fluid flow path (8) and elimination of a physical impediment to fluid flow within the fluid flow path (8).

Again referring primarily to FIG. 2G, FIG. 2H, and FIG. 4G, the helical spring (51) can be disposed between a pair of projecting ribs (52)(53). For example, a helical spring first end (54) can bear against a first rib (52) and an opposing helical spring second end (55) can bear against a second rib (53) outwardly extending from the second conduit outer surface (73).

When in a non-compressed condition (17), which is the normal biased condition, the helical spring (51) can bias the second conduit (63) and correspondingly the second seal assembly (75) toward the engagement surface (76) and correspondingly, toward the second valve closed position (69), thereby sealably occluding the second port (66) and providing the second passageway closed condition (67).

Upon forcible urging in a second direction (57) which opposes the first direction (47), the helical spring (51) can be compressed toward a compressed condition (18), allowing the second conduit (63) to travel within the second valve seat (65) to dispose the second seal assembly (75) away from the engagement surface (76) and away from the second port (66) toward a second valve open position (70), thus providing a second passageway open condition (71) permitting fluid flow through the second port (66) and accordingly, through the second passageway (6) (as shown in the example of FIG. 2G).

Now referring primarily to FIG. 2G, the helical spring (51) can be compressed toward the compressed condition (18) upon forcible urging resulting from connection of the female and male couplers (3)(5), thus allowing the second conduit (63) to travel within the second valve seat (65) to dispose the second seal assembly (75) away from the engagement surface (76) and away from the second port (66) toward a second valve open position (70), thus providing a second passageway open condition (71) permitting fluid flow through the second port (66) and accordingly, through the second passageway (6). Further, upon achievement of the connected condition (7) of the connector system (1), the first passageway (4) of the female coupler (3) can fluidicly communicate with the second passageway (6) to provide the fluid flow path (8) through which fluid can flow between the connector system first and second ends (41)(42).

Now referring primarily to FIG. 5G, FIG. 5H, FIG. 7G, and FIG. 13A through FIG. 14G, as another illustrative example, the second valve-biasing member (68) can be configured as a resiliently flexible member (58); however, the second valve-biasing member (68) need not be limited to this particular configuration.

When in a non-flexed condition (59) (as shown in the examples of FIG. 13A through FIG. 13G), the resiliently flexible member (58) can bias the second valve (64) toward the second valve closed position (69) in which the second valve (64) sealably occludes the second port (66) (as shown in the example of FIG. 5H and FIG. 7G).

Upon forcible urging, the resiliently flexible member (58) can be flexed toward a flexed condition (60) (as shown in the examples of FIG. 14A through FIG. 14G), allowing the second valve (64) to travel within the second valve seat (65) toward the second valve open position (70) away from the second port (66), thereby permitting fluid flow through the second port (66) and accordingly, through the second passageway (6) to provide the second passageway open condition (71) (as shown in the example of FIG. 5G).

As can be easily understood from the foregoing, the basic concepts of the present invention may be embodied in a variety of ways. The invention involves numerous and varied embodiments of a connector system and methods for making and using such a connector system, including the best mode.

As such, the particular embodiments or elements of the invention disclosed by the description or shown in the figures or tables accompanying this application are not intended to be limiting, but rather exemplary of the numerous and varied embodiments generically encompassed by the invention or equivalents encompassed with respect to any particular element thereof. In addition, the specific description of a single embodiment or element of the invention may not explicitly describe all embodiments or elements possible; many alternatives are implicitly disclosed by the description and figures.

It should be understood that each element of an apparatus or each step of a method may be described by an apparatus term or method term. Such terms can be substituted where desired to make explicit the implicitly broad coverage to which this invention is entitled. As but one example, it should be understood that all steps of a method may be disclosed as an action, a means for taking that action, or as an element which causes that action. Similarly, each element of an apparatus may be disclosed as the physical element or the action which that physical element facilitates. As but one example, the disclosure of a “connector” should be understood to encompass disclosure of the act of “connecting”—whether explicitly discussed or not—and, conversely, were there effectively disclosure of the act of “connecting”, such a disclosure should be understood to encompass disclosure of a “connector” and even a “means for connecting”. Such alternative terms for each element or step are to be understood to be explicitly included in the description.

In addition, as to each term used it should be understood that unless its utilization in this application is inconsistent with such interpretation, common dictionary definitions should be understood to be included in the description for each term as contained in the Random House Webster's Unabridged Dictionary, second edition, each definition hereby incorporated by reference.

All numeric values herein are assumed to be modified by the term “about”, whether or not explicitly indicated. For the purposes of the present invention, ranges may be expressed as from “about” one particular value to “about” another particular value. When such a range is expressed, another embodiment includes from the one particular value to the other particular value. The recitation of numerical ranges by endpoints includes all the numeric values subsumed within that range. A numerical range of one to five includes for example the numeric values 1, 1.5, 2, 2.75, 3, 3.80, 4, 5, and so forth. It will be further understood that the endpoints of each of the ranges are significant both in relation to the other endpoint, and independently of the other endpoint. When a value is expressed as an approximation by use of the antecedent “about,” it will be understood that the particular value forms another embodiment. The term “about” generally refers to a range of numeric values that one of skill in the art would consider equivalent to the recited numeric value or having the same function or result. Similarly, the antecedent “substantially” means largely, but not wholly, the same form, manner or degree and the particular element will have a range of configurations as a person of ordinary skill in the art would consider as having the same function or result. When a particular element is expressed as an approximation by use of the antecedent “substantially,” it will be understood that the particular element forms another embodiment.

Moreover, for the purposes of the present invention, the term “a” or “an” entity refers to one or more of that entity unless otherwise limited. As such, the terms “a” or “an”, “one or more” and “at least one” can be used interchangeably herein.

Further, for the purposes of the present invention, the term “coupled” or derivatives thereof can mean indirectly coupled, coupled, directly coupled, connected, directly connected, or integrated with, depending upon the embodiment.

Thus, the applicant(s) should be understood to claim at least: i) each of the connector systems herein disclosed and described, ii) the related methods disclosed and described, iii) similar, equivalent, and even implicit variations of each of these devices and methods, iv) those alternative embodiments which accomplish each of the functions shown, disclosed, or described, v) those alternative designs and methods which accomplish each of the functions shown as are implicit to accomplish that which is disclosed and described, vi) each feature, component, and step shown as separate and independent inventions, vii) the applications enhanced by the various systems or components disclosed, viii) the resulting products produced by such systems or components, ix) methods and apparatuses substantially as described hereinbefore and with reference to any of the accompanying examples, x) the various combinations and permutations of each of the previous elements disclosed.
